Lufthansa has become the first airline to run regular commercial flights powered partially with biofuel.

Airlines have flown many demonstration biofuel flights, but Lufthansa’s LH013 11:15am Hamburg to Frankfurt flight will start the first passenger service to run on a blend of biofuel and conventional fuel.

The company will use the novel fuel mix for six months on eight of its 28 daily 50-minute flights between the two German cities – a distance of 244 miles each way. The German airline says the 1,200 flights will save 1,500 tonnes of CO2.
